It seems like Florida law on condos is a bit quirky, so I'm not sure about this, but this is my reaction to how it works. If a condo association lets a property go to bank foreclosure, the condo association is limited in how much of the outstanding fees it can recover from the later sale of the property. However, if the condo association forecloses on the property, the condo association can then get a lien on the property, and that lien will present problems to the bank selling the property if it later forecloses, making it more likely the condo association gets theirs.
If the condo association forecloses, it possibly could sell, but the bank would have a security interest in the property that would survive the condo association's foreclosure. This security interest, if properly recorded at the Registry of Deeds, would be obvious in any title search. Eventually, if the bank does not collect on its mortgage, and does nothing to collect on it, the collection of the debt can become tolled by the passage of time.
Further complicating this is the fact that the condo association might not know who the current owner of the mortgage is. And interestingly, it doesn't seem to be the policy in Florida to have the bank collect the condo fee with the mortgage.
However, for the less than honest, who are capable of finding the more than stupid, who have a corrupt attorney on tap, you could have some real fun. This would work especially well with second homes where the owner is out-of-state.
Condo association forecloses on the unit, which provides a legitimate set of documents to start with. The president approaches prospective buyer with a really good deal on a condo. Buyer has corrupt attorney, who is recommended by president of condo association, who says the title is clean, ignoring the mortgage that is clearly on file.
As long as the bank doesn't realize what's going on, this happy state of affairs could go on for quite a while. The way some banks have lost track of their mortgages, they might never catch up with the fact.
If your buyers are taking advantage of this deal because they're sort of sleazy, figure there's something rotten in Denmark, but don't care as long as they can get by for a while, you could have some fun.
And it takes advantage of the well known propensity of banks to sell mortgages, and then lose track of them. There's a lot of people in foreclosure who can't figure out who the hell they should be paying and how they got there. Some of these mortgages have been through several hands, and the paperwork on them is hard even for the bank to trace.
Best of luck,
